Electrical connection
Depending on the model, the electrical connection is made
using a cable or a connector.
The connection or pin assignments for the respective
version can be found in Table 4-3.
Note the information on shielding and cable
routing on page 10.

Unassigned leads can be connected to the GND on the controller side but not to the shield.
1)
2)
Because of the separate output drivers there are small voltage differences between pin 3 and pin 5 (constant offset < 10 mV).
Reference potential for supply voltage and EMC-GND.
3)
The transducer outputs are potential-free. Connecting to a controller with non-potential-free inputs may result in GND loops and malfunctions. This can be
4)
prevented by connecting pin 2 and pin 6 to each other in the connector in order to disable the potential separation in the transducer (see Figure 4-9).
